Effect of select medium supplements on in vitro development of Cryptosporidium andersoni in HCT-8 cells.
Article in Parasitology research, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We evaluated the effect of fetal calf serum (FCS), glucose, ascorbic acid, calcium pantothenate, folic acid, and insulin on the growth of Cryptosporidium andersoni in human colon tumor (HCT-8) cells. After being incubated for 48 h, the proliferation of parasites was determined by real-time polymerase chain reaction (PCR) assay, and the development of C. andersoni was observed by transmission electron microscopy (TEM). Ten percent FCS was the best concentration for C. andersoni culture. Glucose, ascorbic acid, and insulin had a significant effect on the growth of C. andersoni when added into 10% FCS RPMI 1640. Calcium pantothenate had no significant effect and folic acid had the inhibited effect. We also observed the stages of trophozoite, macrogamont, microgamont, type I meront, type II meront, and sporozoite of C. andersoni in HCT-8 cells by TEM. Our results indicated that the best medium for C. andersoni was 10% FCS RPMI 1640 medium containing 50 mM glucose, 50 microg/ml ascorbic acid, and 0.3 U/ml insulin. Real-time PCR could provide a quick and precise technique to determine the proliferation of parasites. Cultivation of C. andersoni in HCT-8 cells will facilitate the study of interactions between parasites and host cells as well as provide a reliable system for evaluating anticryptosporidial compound efficacy.
